Answer

2 lbs

Work Step by Step

Uncooked rice equals $\frac{4}{13}$ of cooked rice. We need to make 6.5 pounds of cooked rice.You have to figure out how much-uncooked rice is needed.
X equals the # of pounds of cooked rice that is needed. Thus;
x=$\frac{4}{13}$ $\times$ 6.5 (change the fraction to a decimal to make it easier to multiply)
x=0.31 $\times$ 6.5
x=2.015
Since you can't have 2.015 pounds you round it to 2lbs.
